100 Offline Games

100 Classic Games — Fully Offline, Right in Your Browser

Open the extension, pick a game, and play. No accounts. No downloads.
No internet connection required. Everything runs locally inside Chrome.

HOW IT WORKS
The extension bundles a compact, open-source emulation engine (Genesis Plus GX)
together with 100 classic Genesis / Mega Drive games. When you click a game tile, the engine loads the game entirely from your local storage — nothing is fetched from any server.
The emulated console runs inside a sandboxed HTML page, so gameplay starts
in seconds without any installation wizard or extra software.

WHAT'S INSIDE
• 100 hand-picked titles across 8 genres
• Platformers — run-and-jump adventures spanning multiple sequels and studios
• Beat Em Ups — side-scrolling brawlers for one or two players
• Action — ninja warriors, robots, dolphins, and alien invasions
• Fighting — legendary arcade one-on-one combat ports
• Shooters — vertical and horizontal shoot-em-ups with intense bullet patterns
• RPG — turn-based and action RPGs with rich storylines
• Sports — basketball, football, and golf classics
• Racing — motorbike road races and miniature car championships

CONTROLS
The keyboard is mapped automatically: Arrow keys move your character,
Z / X / A / S handle action buttons, Enter = Start, Shift = Select.
Gamepad controllers connected via USB or Bluetooth are also supported
through the standard browser Gamepad API — plug in and play.

BROWSING YOUR LIBRARY
Use the search bar to filter games by name, or click the genre buttons
(All · Platformer · Beat Em Up · Fighting · Action · Shooter · RPG ·
Sports · Racing) to narrow down the list. Click any game card to launch it.
Press the Back button inside the player to return to your library.

artwork are bundled locally. No data is collected, stored, or transmitted.
